Liaison Reports

Nothing to report...

License Management

Michael led a discussion of the section on License Checks and Lifetime. John clarified that we are really looking to refine the spec for the licensing pragmas and that opportunities to unload dynamic libraries were an implementation quality concern rather than a correctness issue.

John raise concerns about what will happen as license use scales with growth in IP use. Licensing to identify real customers is likely to be cheaper than managing use of specific activities/functions within a flow. An alternative to management via licenses is to provide alternative distributions with the appropriate authorizations, though that has its downsides as well. Flexibility in functionality can be moderated by recommendations on how to use that flexibility in a cost-effective way. Feedback from IP suppliers in the meeting suggest that there is no immediate need for heartbeat to manage concurrent use. Absent other feedback, our recommendations should guide IP authors away from heavy use of this capability.

Key Management Issues

Nitin reviewed progress in key management, and asked for feedback on the high-level direction. Michael suggested that a narrative description of the use model would be helpful in getting feedback from those outside the working group. John asked for analysis of how choices made by the Certificate Authority would compromise our use of the certificate and its various data fields.
